Application filed March 8, 1887. Serial No. 230,154. (No model.)

.To all whom it may concern.-

Be it known that I, ALFRED BRANDRIFF, a citizen of the United States,residing at Millville, in the county of Cumberland, State of New Jersey,have invented a new and useful Improvement in Machines for Edging andScanning Plates, which improvement is fully set forth in the followingspecification and accompanying drawings.

My invention consists of a machine for edging and seaming metal plates,embodying means for bending the plates, joining the same and rollingthem on a reel or drum, and other features, as will be hereinafter fullyset forth.

Figure 1 represents aside elevation of a machine for edging platesembodying my invention. Fig. 2 represents a top or plan view thereof.Figs. 3 and 4 represent vertical sections of the seam-closing mechanismthereof on lines or w and y y, respectively, Fig. 2. Figs. 5 and 6represent transverse sections of the mechanism employed for throwing therolling device in and out of gear on line z 2, Fig. 2.

. Fig. 7 represents a transverse section of the straightening device online a a, Fig. 2. Figs. 8 and 9 represent partial side elevations andpartial vertical sections of the bending or edging mechanism on anenlarged scale. Fig. 10 represents a vertical section of the adjustingdevice of the bending or edging mechanism. Fig. 11 represents a top orplan view of the bending or edging blade and horizontal section of thestuds,pins,or shoulders with which said blade engages, the parts beingon a reduced scale.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings, A represents the frame of the machine, thesame having mounted on it the driving-shaft 1, which carries the crank2, whereby, by means of the treadle 3, power is communicated to saidshaft 1. Geared with the shaft 1 is a shaft, 4, to which is secured thecam 5, which is adapted to bear against an arm, 6,the latter beingmounted on the frame A, and carrying at its outer end a blade, 7, whosesides have recesses 8, as will be seen in Fig. 11.

At the top of the frame of the machine is mounted a roller, 9, and abovesaid roller is a head, 10, which is pivoted or hinged to the frame andrises and falls to a limited extent.

To the frame are attached catches l1,which rest over the ends of theside pieces, 12, of the head 10, opposite to the axis thereof,wherebysaid head is prevented from rising. By turning the catches on theirfasteningspins or scrcws-they clear the side pieces, 12, and permit thehead to be raised, whereby the roller 9 and adjacent parts of themachine are accessible for purposes requiring the same.

Beneath the head 10 is abutment 13, which is slotted and screwed to ablock, 14, on the frame by means of a screw, 15, which passes throughthe slot of the abutment and enters said block 14, said abutment, as isevident, being vertically adjustable. Secured to the under side of thehead 10 are pins or studs 16, which are adapted to be engaged by thewalls of the recesses 8 of the blade 7. Below the roller 9 is a table,17, above which is a weighted or gravitating arm, 18, whose lower endapproaches said table, the upper end of said arm having a handle, 19,which is accessible at the side or top of the frame, whereby the arm maybe readily raised as desired. As will be seen in Fig. 8, the arm permitstwo contiguous sheets or plates of metal to pass under the same, butprevents more than that number from passing, it acting as a sweeper orclearer for that purpose, as is evident.

It will be seen that as the shaft rotates the cam 5 bears against thearm 6 and raises the same, causing the blade 7 to enter between the head10 and the face 20 at the top of the block 14.

Mounted on the frame A is a shaft, 21, which is operated by the shaft 1by means of intermediate gearing, and carries a drum, 22, and agear-wheel, 23, the latter meshing-with a pinion, 24, which is mountedon the frame A, and has loosely fitted on its axis an elbow, 25, thelatter forming the bearing for a shaft, 26, which carries a gear-wheel,27, having its periphery adjacent to the periphery of a gearwheel, 28,the latter being secured to the shaft 29, which is mounted on the frameA and carries the reels or drums 30, on which the plates as edged arewound or rolled.

Rising from the table A are guides 31 for vertical sliding boxes 32, inwhich is j ournaled the depending segmental arm 33, whose peripheralface 34, when in normal position, is above and in advance of theperiphery of the roller 22. (See Fig. 3.) Connected with-one of thejournals, a, of the arm 33 is an arm, 35, from which depends a weight,36, the rod 37, which is connected with said arm 33 and the weight 36,having attached to it near its upper end a stop, 38, which is adapted toabut against an adjacent portion of the frame A, so as to limit therising motion of the segmental arm 33. (See Fig. 1.) To theotherjournal, a, of the arm 33 is secured acrank, 39, whereby said arm33 may be readily operated by hand.

At the side of the receiving end of the table 17 is an elbow-lever, 40,the vertical limb of which passes through said table and projects abovethe same. (See Figs. 5 and 6.) The horizontal limb of said lever ispivotally connected with a lever, 41, which is mounted on the table A,and has one end carryinga weight, 42, whereby the lever 40 is heldinclined in its normal position, as shown in Fig. 5. The lever 40 hasconnected with it a spring, 43, to assist the return motion thereof, anda handle, 44, for conveniently operating said lever.

In the table 17 are openings 1) to receive blocks 45, each of whichmaybe connected by a strap or link,46,(shown in dotted lines,) with thelever 40, thus adapting said lever to be operated with plates ofdifferent widths, as will be hereinafter more fully set forth. At theside of the discharge end of the table 17 is a gravitating elbow-finger,47 whose upper limb passes through an opening, 48, in said table andprojects above the same.

In the table 17 are other openings, 49, and the finger 47 may be removedin order to be mounted adjacent to either opening 49, so as to beoperative therein, the object of said finger being to keep the platesstraight and true as they move over the table to the winding reel ordrum, the openings 49 permitting the finger 47 to adjust itselfrelatively to plates of different widths. The weighted lever 41 isconnected by a link, 50, with the arm 25, whereby as the weighted end ofsaid lever rises the wheel 27 also rises and is caused to mesh with thewheel 28, whereby motion may be imparted to the shaft 29, andconsequently to the reels 30. The shaft 29 carries a ratchet, 51, withwhich engages a pawl, 52, mounted on the frame A, whereby reverse motionof the shaft, and consequently of the reels 30, is prevented, it beingnoticed that the shaft is removably mounted in its bearings 011 theframe A.

The sliding boxes 32 of the segmental arm 33 are held in position bymeans of screws 53, which are fitted to the-cross-bars at the top of theguides 31 and bear against said head.

\ Springs 54 bear upwardly against the boxes 32 to raise the same whenreleased by the screws 53.

The operation is as follows: The machine is set in motion by means ofthe treadle 3 or any other suitable power, and a sheet or plate of metalintroduced between the roller 9 and head 10, and carried by said rolleruntil its front -tion of the arrows of said figure.

edge strikes the shoulder formed by the abutment 13 and block 14, aswill be seen in Fig. 8. The cam 5 now bears against the arm 6 and forcesthe blade 7 toward the under side of the plate, near the end thereof, inthe direct This bends the end portion of the plate and forces the samebetween the under side of the pivotal end of the head andthe upper faceof the face of the block 14, thus formingahook on the end of a plate, asis shown near the top of Fig. 9 and at the lower left-hand corner ofFig. 8. When the blade first strikes the metal blank or plate and beginsto bend the same, the wallsof the recesses 8 at the sides of said bladecome in contact'with the pins or studs 16 on the head '10, and thus movethe head downwardly on its axis, so that the head advances toward theblank resting on the blade 7 -and firmly presses the same thereagainst.The cam 5 now leaves the arm 6,and the latter, owing to its weight,drops or lowers and leaves the hook portion of the plate, the head 10then rising and widening the space-occupied by the hooked end of theplate, this being due to the action of the spring c,which rests on theframe A and bears upwardly against said head, whereby binding of thehooked end of the plate between the head and face 20 is prevented. Theplate is now removed and reversed and again introduced beneath the headand subjected to operations similar to those stated, the result being aplate edged or having on its end hooks bent in opposite directions. Anumber of plates are hooked together, placed on the table 17 andadvanced on the latter to the reels 30, where the hook of the firstplate is connected with hooks (Z on the inner periphcries of said reels.As a blank-plate is placed on the table 17, it is rested against aflange or shoulder on one side of the same and. forced against theprojecting end of the lever 40. This forces said end outward and lowersthe horizontal limb thereof. This raises the arm 25, whereby the wheel27 is carried to the wheel 28 and caused to mesh therewith, so that thereels are rotated and the plates are drawn along and wound on said reel,forming a roll of continuous plates. When the hooks of two connectedplates reach the face of the segmental arm 33, they bear against thevsame (see Fig. 3) and advance said arm, said arm occupying a tangentialposition to the roller 22. The arm now assumes a radial position inrelation to said roller, whereby the hooks of the two plates aresqueezed and united,(see Fig. 4,) the plates then continuing theirmotion. When the hooked portions of the plates clear the arm 33, thelatter returns to its normal position, as in Fig. 3, due to the actionof the weight 36. As the plates leave the roller 22, they are guided onthe table 17- by means of a flange or shoulder on one side of the sameand the finger 47, the latter moving or yielding as the edge of eachplate rides on the same, thus exerting its pressure against said edgeand causing the plateto move true, and thus be fed uniformly to thereel. Then the ends of a plate clear the lever 40, the latter isimmediately controlled by the weighted lever, and said lever returns toits normal position. The weighted end of the lever 41 descends, thuslowering the wheel 27 and disengaging it from the wheel 28, thusstopping the reeling or rolling operation. As soon, however, as anotherpiece of hooked metal is attached to the advancing plate, the lever 40is thrown out and the lever 41 is again operated, whereby the reeling orrolling operation continues.

When a roll of sufficient size is produced, it may be bound by a strap,band, cord, &c., and removed with the shaft 29 from the bearing of thelatter, after which said roll is slipped off the reel endwise, and thelatter with its shaft may then be restored, ready for the formation ofanother roll.

The upper face of the abutment 13 is preferably rounded, and the edge ofthe metal plate rides on the same as it turns during the bending actionofthe blade 7, thus preventing dropping and displacement of the plate.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
